First day of winter 2015 Digital Library Object - Graphics-oriented battlefield tracking systems: U.S. Army and Air Force int Introduction In this , we describe the theory of evolution by natural selection as proposed by Charles Darwin in his book, first published in 1859, On The Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life. We will look at natural selection as Darwin did, taking inheritance for granted, but ignoring the mechanisms underlying it. Introduction This course is an introduction to chemistry concepts, using water as the main illustration. Much of the course is devoted to exploring the smallest water particle - a water molecule - what it is and how it gives rise to the particular properties of water. The course also explains powers of ten and scientific notation, which are a convenient way of expressing both very large and very small numbers. It is a good introduction to science. This OpenLearn course provides a sample of level 1 s Introduction Nature Matters considers environmental responsibility and what may matter from a caring perspective and an accountability perspective. A reading by Andrew Light reflects on four key debates in environmental ethics regarding the way in which nature is valued, and prompts the question on how such debates might inform environmental responsibility. Section 2 examines the formal processes involved in developing accountability in the context of sustainable development. The persuasiveness of t 6 Phylogeny and cladistic analysis In Section 3.3 the point was made that many physiologists consider that desert birds are successful because of their avian physiology, not because of any specific adaptations. While Williams and Tieleman's research on hoopoe larks demonstrated that desert species are capable of flexibility in metabolic rate and evaporative water loss, it suggested that adaptation is important too. The selective advantages of lowered BMR and TEWL for desert birds include reduced energy demand, and lower produc 1 Wave energy The energy carried by ocean waves derives from a proportion of the wind energy transferred to the ocean surface by frictional drag. So, ultimately it stems from the proportion of incoming solar energy that drives air movement. Just how much energy is carried by a single wave depends on the wind speed and the area of ocean surface that it crosses; wave height, wavelength, and therefore wave energy, are functions of the distance or fetch over which the wind blows. Not surprisingly the ma Design Introduction ‘Environment’ is one of the more popular words in the management lexicon, most generally understood to be referring to ‘something outside’. But common usage today often interprets the Environment (with or without the capital ‘E’) as referring to the planetary ecosystem. On that basis the Environment includes such things as global warming, the state of the ozone layer, deforestation and the means of energy generation.

Darwin Now Awards Topic 5: Income Taxation and Labor Supply part 3 | Economics 2450A: Public Economics 9.2 Lennox Castle Hospital This course looks at the history of institutions in the twentieth century, starting with a case study of Lennox Castle Hospital. It tries to make sense of the history of Lennox Castle, and of institutional life in general, through testimony of those who experienced institutions as inmates and as nurses, as well as through Erving Goffman's model of the ‘total institution’. It examines the social bases of segregation, the professionalisation of staff in asylums and institutions, and campaig Reuters Today: Europe deal hands ECB watchdog role 18.904 Seminar in Topology (MIT) The architecture of refugee protection Big Avalanche on Mount Sefton!

This free course looks at the process of design, from assessing the complexity of design as an activity to exposing the difficulty in making general conclusions about how designers work. You will be able to identify innovation in a wide variety of designed objects and evaluate the impact of this innovation.

Sweatshops and the exploitation of workers are often linked to the globalised production of ‘big brand’ labels. This unit examines how campaigners have successfully closed the distance between the brands and the sweatshops, while others argue that such production ‘kick starts’ economies into growth benefiting whole communities.

Dec. 13 - Europe reaches a deal to give the ECB new powers to oversee the bloc's banks. U.S. Fed says interest rates will stay near zero until unemployment falls to at least 6.5%, boosts monthly bond buying.
This course is a seminar in topology. The main mathematical goal is to learn about the fundamental group, homology and cohomology. The main non-mathematical goal is to obtain experience giving math talks.

Mount Sefton in New Zealand has a high ice cliff across the East Face. When the ice moves it has nowhere to go but down! This video shows an avalanche falling down the side of the mountain. (01:14)
